Welcome to NPs @Aldamar! I hope that this community will be everything that you hope and need. It is full of knowledgeable people who often have competing opinions, but almost all of whom are happy to share their expertise and knowledge.
Why don't you tell us a bit about what niches, etc. interest you, and what you most hope to get from NPs?
Good luck with your first domain. Be sure to take some time to read and learn before you buy a lot of domains. That will probably save you money down the road.
